48 results for n-fold vector bundle

This paper introduces \infty- and nn-fold vector bundles as special functors from the \infty- and nn-cube categories to the category of smooth manifolds. We study the cores and "n-pullbacks" of nn-fold vector bundles and we prove that any nn-fold vector bundle admits a non-canonical isomorphism to a decomposed …

Vector bundles and double vector bundles, or 22-fold vector bundles, arise naturally for instance as base spaces for algebraic structures such as Lie algebroids, Courant algebroids and double Lie algebroids. It is known that all these structures possess a unified description using the language of super\-geometry and g…

Double vector bundles may be dualized in two distinct ways and these duals are themselves dual. These two dualizations generate a group, denoted DF2\mathscr{D}\mathscr{F}_2, which is the symmetric group S3S_3 on three symbols. In the case of triple vector bundles the authors proved in a previous paper that the correspon…

We calculate the group of dualization operations for triple vector bundles, showing that it has order 96 and not 72 as given in Mackenzie's original treatment. The group is a nonsplit extension of S4 by the Klein group. Dualization operations are interpreted as functors on appropriate categories and are said to be equa…

A natural explicit condition is given ensuring that an action of the multiplicative monoid of non-negative reals on a manifold F comes from homotheties of a vector bundle structure on F, or, equivalently, from an Euler vector field. This is used in showing that double (or higher) vector bundles present in the literatur…

In Physics and in Mathematics Z2n\mathbb{Z}_2^n-gradings, n>1n>1, appear in various fields. The corresponding sign rule is determined by the `scalar product' of the involved Z2n\mathbb{Z}_2^n-degrees. The Z2n\mathbb{Z}_2^n-Supergeometry exhibits challenging differences with the classical one: nonzero degree even coordinate…

Let XX be a complex toric Fano nn-fold and N(T){\cal N}(T) the normalizer of a maximal torus TT in the group of biholomorphic authomorphisms Aut(X)Aut(X). We call XX {\em symmetric} if the trivial character is a single N(T){\cal N}(T)-invariant algebraic character of TT. Using an invariant αG(X)α_G(X) introduced by Tian, we …

We explain that general differential calculus and Lie theory have a common foundation: Lie Calculus is differential calculus, seen from the point of view of Lie theory, by making use of the groupoid concept as link between them. Higher order theory naturally involves higher algebra (n-fold groupoids).(conceptual, topol…

A triple vector bundle is a cube of vector bundle structures which commute in the (strict) categorical sense. A grid in a triple vector bundle is a collection of sections of each bundle structure with certain linearity properties. A grid provides two routes around each face of the triple vector bundle, and six routes f…

We consider a diffeological counterpart of the notion of a vector bundle (we call this counterpart a pseudo-bundle, although in the other works it is called differently; among the existing terms there are a "regular vector bundle" of Vincent and "diffeological vector space over X" of Christensen-Wu).
